How to create a singular cookie (HELP!)
So I recently started to work with web. I need your help. I need to create a cookie who can remmember what a visitor chose in accessibility tab. I was reading a lot about them and still I'm not so good programmer I guess :D I started like this:
<?php
add_action( 'init', 'accessibility' );
function accessibility() {
setcookie($visitor_ip, $ip_value,7 * DAYS_IN_SECONDS);
}
?>`
but idk if it is right. After that idk how to call him that he will remmember this..:
<?php
if(!isset($_COOKIE[$visitor_ip])) {}
else {}
?>`
If you can help me, would be wonderful. Website: web.kga.lt
union of two query return null when one of query result is empty. how to handle it?
i have a query where i wrap two query by union in another select query for example:
select A,B from (select x,y from firsttable where bla bla bla
union
select C,D from secondtable where bla bla bla) group by Z;
Now when firstTable or secondtable have empty result because of where condition then it return result as
1st row> NULL | NULL | NULL
2nd row> 1 | 2 | 3 <- this is result of second or first (but one table) when one table where clause have something to return.
note: when both where condition have values to return then no such problem. the problem occre only when one of wrapped query return empty set. when both where query have values then it give desirable result which is only one row because it is grouped
Force use of browser's right click menu instead on CKEditor's ContextMenu?
I need to add contextmenu due to various table plugins (i need contextmenu), but I want to use the default browser right click due to spell checking / suggestions.

Is this even possible?
Integrating REST APIs within an Angular 6 Application
I am working creating a new Angular 6 application. The back-end for the application is Spring. I am expected to consume the backend REST APIs at the frontend. Please advice on the configuration required to achieve the same with in the Angular Application. Below are few changes that I can think of to be made at the frontend:
-
Importing the HttpClientModule with in the app.module.ts
-
Configure the environment.ts & environment.prod.ts files with the apiurl information
- Create a rest api service to call various end point
Can anyone suggest on the right steps for the REST API consumption starting from scratch. Are there any configurations required in package.json or any other files ?
Please advice !

Is web browser JavaScript runtime?
In Node.js website, they say Node.js is a JavaScript runtime.
Are web browsers like Chrome, Firefox, Edge, ... JavaScript runtimes?
I thought of course, web browser is JS runtime. But I'm confused, In this video 12:10~ He says Web browser is not just JavaScript runtime because it can do more things at one time, it can give us other things.
But I think V8 engine only can do one thing at one time, while JS runtime can do more things than one at one time.
Am I wrong?
Python 3 md5 hashes in webpage
I'm building this md5 password crack to find hashes hidden in a webpage. My url page is in a separate file while im using the function (html) to call the website in order to find and crack the hashes. I'm kind of stuck on how to finish off the code, at least to find the hashed without cracking them at this point. This is my code to find the hidden hashes. Thanks
def dictionary_attack(html):
dictionary = ['qwerty','qwerty1','password','password1','default','default','123','12345','123456']
password_found = False
for dictionary_value in dictionary:
hashed_value = (hashlib.md5(dictionary_value)).hexdigest()
if hashed_value == password_hash:
password_found = True
recovered_password = dictionary_value
if password_found -- True:
print ('Found \n',password_hash)
print ('password rec' , recovered_password)
else:
print ('pass not found')

how to make a line as a pseudo element?
So, I have stuck on this one. At the picture below you can see what should I do. However, I don't really understend how to make those crossed lines between the divs.
Here is the code I have done so far: https://codepen.io/kaeses_developer/pen/wxyYdb
As I think, I have to create :before and :after pseudo element for .menu-item--large.
.menu-item--large {
flex-basis: 100%;
font-size: 36px;
background: none;
margin: 0 50%;
}
But how do I do it right? Or are there any different ways to make it?
Webpage styling disappears when using it in JSP
I have an issue displaying a dashboard developed using few javascript libraries and CSS files. Whenever I check the html file it looks amazing with the styling and colors. The problem is when i use the same HTML code as part of my JSP page all the styling just goes away.
HTML code:

Extract anchor links from a list of html links
I have a list of html page links. Each one leads to a page (different one accordingly). Whats common is that all pages contain a link leading to a google drive pdf direct download document. So I want to get these google drive links from every html link in the list in one go so that I can bulk download them.
My list looks like:
https://www.link....../....html
https://www.link....../....html
https://www.link....../....html
https://www.link....../....html
https://www.link....../....html
Can anyone show me a sufficient way? I'm still new to programming :)
How do I assign fetch data to $scope.variable
I am fairly new to both javascript and angular. My code retrieves data from an API and can print it to the console, but when I try to assign it to $scope.saveData, it only works inside the fetch. I've gotten as far as understanding that my problem has something to do with the code running asynchronously and the way promises work, but I can't seem to find any resources that work to solve my problem. Here is my code.
Angular
angular.module('myApp',[])
.controller('testCtrl',['$scope', function($scope){
const response = await fetch("http://localhost:3000/conferences").then(res=>{
// $scope.saveData = null;
if(res.url == "http://localhost:3000/outlook"){
res.json().then(data=> {
window.location.replace(data.url)
})
}else{
res.json().then(data=> {
$scope.saveData = data
console.log($scope.saveData)
});
}
});
console.log($scope.saveData)
}]);
html
<!DOCTYPE html>
<html ng-app = 'myApp'>
<head>
<title>Scheduled Calls</title>
<link rel="stylesheet/less" type = "text/css" href="./scheduledCalls.less" />
</head>
<body>
<header style="text-align: center">
<h1 class = "header" >Scheduled Calls</h1>
</header>
<div ng-controller="testCtrl" >
<p></p>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src = "scheduledCalls.js"></script>
</body>
</html>
the console.log under $scope.saveData = data works. It does not work for the console.log at the bottom of the js code.
I'm not getting the right random value. There are 6 values in my database. I give Limit 3. But the first 4 items shows randomized
I need 3 question from 6. but every time randomize show fast 4 question.
/*for random question*/
public function qustionShow($question){
$query = $this->conn->query("select * from question where cat_id='$question'");
$c = mysqli_num_rows($query);
$rand = rand(3, $c)-3;
$show = $this->conn->query("select * from question where cat_id ='$question' and id >'$rand' LIMIT 4");
while ($row=$show->fetch_array(MYSQLI_ASSOC)){
$this->qus[]=$row;
}
return $this->qus;
}
Should file scheme behave exactly the same as http?
What interests me is whether there is a documented set of differences that one should expect in a client browser when accessing some site using those two different schemes (http and file). I assume this site is available for both http and file.
Angular 5 - selected option not shown on top of dropdown list
I have 3 contacts which is displayed on dropdown list and an optional value "Please select contact person" as can be seen below.
However, when page loads it shows the last entry in the dropdown list. Optional value "Please select contact person" should rather be shown as default initial value when page initially loads.
Component template for the dropdown list is setup as follows:
<div class="col-lg-6" *ngIf="dealer.contacts && dealer.contacts.length" >
<label>Contact person</label><br>
<select class="form-control" [ngModel]="survey.answer.contact.email" (ngModelChange)="onContactChange($event)">
<option selected [ngValue]="null">Please select contact person</option>
<option *ngFor="let contact of dealer.contacts" [ngValue]="contact.email"> , </option>
</select>
</div>
Component class method related to the ngModelChange is as shown below. Please note that $event value is email and when it is null, an empty object is sent back - please let me know if you have comments on this as well.
onContactChange(email: any){
if (email) {
var contact: any = this.survey.answer.contact;
if (contact && contact.email == email) {
return;
}
this.survey.answer.contact = this.dealer.contacts.find((contact: any)=>{
return contact.email == email;
});
if(this.survey.answer.emailStatus != '') {
this.survey.answer.emailStatus = '';
}
this.updateSurveyContact();
} else {
this.survey.answer.contact = {};
}
}
Which data is collected by Google Analytics PageView?
I am reviewing the privacy of data collected by Google Analytics when collecting on the default PageView action. Here is the code snippet being used:
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-1111111-11', 'auto');
ga('send', 'pageview');
</script>
I can't find any clear answer as to exactly which data is being collected. I want to make sure that no PII or PHI will be collected by accident if the page being tracked contains some, such as name, phone, medical info, etc.
Is there any clear guide that states which data is collected for PageView?
how to bypass form filling of asp form with direct http request
As i guess, filling an asp form will finally pack all data filled and make a post request to a certain url to update the data. How could i bypass the form filling efforts and pass the required values with other external methods, e.g via making http request. How could i investigate what have to pass and what the destination url of the form is.
I have tried to look into the html scripts but could only know the web will trigger a javascript when pressing the button. However, i have no clue on the next step.
Thanks!!
What is a good video platform that I can capture user data from?
I am looking at creating an online university that will offer on demand videos as an option for attendance. However, in order to ensure that the information was covered and the user actually watched the video we need to be able to capture playback data for the user. Essentially if a video is 10 minutes long we need to be able to capture data in order to determine that the user watched 90% of the video before considering the user to have attended the class.
So I'm currently in search of a either a video plugin or platform that can give us the data we need to complete this. I'm open to options here.
How to write your own search for your website from URL
I have seen that you type domain name to the url and put a space, then the website automatically waits for you to enter the string to be searched.
http://i.prntscr.com/g0-tLmvhTCCnBwyh7J0zKQ.png
For example: type youtube.com to the URL bar from your browser then put space character then type your search string.
How can I do that for my website?

Web: Redirecting to a webpage with data(not as URL or query params)
I have a webapp, say, example1.com and the user logged into it. I have the user data in my localStorage. After a particular event, say, button click, I want to redirect the user to example2.com with the user data from localStorage. But the user data shouldn't be sent as url or query params. It shouldn't be visible to the enduser at all.
What are the ways we can achieve this ?

how to join two query result and grouped it by a column
i have query joined by union and it give me desirable result separatly in rows i want to join those two rows and add its values but i dont know how to do it
the query is
SELECT `b`.`main_code`,`b`.`account_title`,SUM(CASE WHEN `a`.`type`='CP' AND `a`.`interactive_person`='6'
AND `a`.`date` BETWEEN '2018-02-12' AND '2018-07-31' THEN `a`.`balance` ELSE 0 END) AS `credit`,
SUM(CASE WHEN `a`.`type`='CR' AND `a`.`interactive_person`='6' AND `a`.`date` BETWEEN '2018-02-12'
AND '2018-07-31' THEN `a`.`balance` ELSE 0 END) AS `debit`, SUM(CASE WHEN `a`.`type`='CR' AND
`a`.`interactive_person`='6' AND `a`.`date` BETWEEN '2018-02-12' AND '2018-07-31'
THEN `a`.`balance` WHEN `a`.`type`='CP' THEN -1 * `a`.`balance` ELSE 0 END) AS `balance`
FROM `vouchers` AS `a`,`data` AS `b` WHERE `a`.`interactive_person`='6' AND `a`.`post_status`='yes'
AND `a`.`interactive_person`=`b`.`main_code` AND `a`.`date` BETWEEN '2018-02-12' AND '2018-07-31'
UNION
SELECT `b`.`main_code`,`b`.`account_title`,IFNull(SUM(`a`.`debit`),0) AS `debit`,
IFNull(SUM(`a`.`credit`),0) AS `credit`, (`debit` - `credit`) AS `balance` FROM `journal_vouchers` AS `a`,
`data` AS `b` WHERE `a`.`account_id`='44' AND `a`.`date` BETWEEN '2018-02-12' AND '2018-07-31'
AND `post_status`='yes' AND `cancel_status`='off' AND `a`.`account_id`=`b`.`account_code`
GROUP BY `b`.`main_code`;
the query is a bit complex let me explain it little: this query takes the result from 3 tables but main thing is that before union its take result from two table and after union two tables in which one table data interact with both. in short the result i get is
main_code | account_title | credit | debit | balance
6 | cash account | 5200 | 520 | -4680
6 | cash account | 0 | 200 | -200
i want the full query grouped by maincode but i dont know how do it i want result to be
6 |cash account | 5200 | 320 | -4880

JavaFX: How to check if page available or not
In my project I use simple JavaFX browser, that works in background and do some stuff without displaying it.
More precisely it submitted some form to one online page.
So, I ran into a problem: when this page doesn't available, I can't figure it out from my Java code, it looks like form wasn't submitted and clicks on Submit button do nothing, but in Chrome for example I see that the page isn't available.
So, is there an option to check from Java code if page is available?
Thanks in advance and sorry for bad English.
My website was hacker copied + database run realtime
My website is being hacker copied code + database real time. When I change the html: website name, the other website also changes. They can customize javascript, css, edit html on copy version in another domain. I checked they do not use an iframe. They can use this domain to index the sitemap just like my website but for the purpose of tricking users into clicking on the download button in their domain. My server is secure, the website uses SSL. Does anyone know what kind of attack this is? How to overcome and prevent?

SQLAlchemy Pandas Flask Slow
After doing some testing with Flask running a webpage, I've noticed that when I connect flask to a database using SQLAlchemy, it takes about 40s to load the page.
zengine = sqlalchemy.create_engine("oracle+cx_oracle://CONNECTION")
summary_sql = "select distinct hub, value, date_inserted from ZE_DATA.AESO_CSD_SUMMARY order by date_inserted desc fetch first 10 rows only"
summary = pd.read_sql_query(summary_sql, zengine)
Is there a way to optimize the code or is there a better option of connecting to a database that would improve the speed?
Thanks!
are there scenarios (i.e. browsers) that it matters the trailing backslash in base tag
Is there any browser that handles differently the values of the <base> tag?
Are
<base href="http://www.example.com" />
and
<base href="http://www.example.com/" />
the exact same thing in all modern browsers? (notice the trailing slash in the second example).

Does choice of programming language affect protection against DoS, specifically Ping Flood?
I am building a REST website and have to pick programming tools based on their protection against DoS, specifically Ping Flood.
I have searched multiple blogs and read research papaers on IEEE; however, none of them mention how choice of programming language affects DoS protection.
Is there any difference between Java Spring Boot, Ruby on Rails, MEAN stack or other framework I haven't mentioned from the perspective of defence agaisnt Ping Flood?
I would like to leave Firewall aside, for research purposes.

How to send the value of Radio Button with Ajax to PHP when selecting
my problem is when I sent my variables through ajax to my .php. The variable 'data.estado' marks me an error once it returns, I already could bring the element that selects and obtain its value but there is an error in my return of ajax data. I do not know what it is. A help please and thanks for giving me a return to my question hehehe :).
My ajax code and controlling the selected radius:
var ComprobarSeleccion = false;
$('input[type=radio][name=radioStacked]').change(function(){
ComprobarSeleccion = true;
$.ajax({
url: "cuestionario.php",
type: "POST",
data:{ valor:this.value, verificar:ComprobarSeleccion},
dataType:"jsonp",
jsonp:"jsoncallback",
contentType:'application/json; charset=utf-8',
crossDomain: true,
cache: false,
success:function($data){
//unselect(this);
//console.log($data.estado);
if($data.estado=="seleccionado"){
alert("Exito");
}
console.log($data.estado);
},
error: function($data){
alert( "Error en la petición: " + JSON.stringify($data));
}
});
});
My PHP code where I try to catch the value of the radio button:
<?php
session_start();
if(isset($_SESSION['sesion_iniciada']) == true ){
$id_alumno = $_SESSION['alumno'] ;
$datos = array();
$a = false;
if(isset($_GET['verificar']) && !empty($_GET['verificar'])){
if($_GET['verificar']){
$valor = $_GET['valor'];
$a = true;
$datos["estado"] = "seleccionado";
//var_dump($datos);
}else{
$datos["estado"] = "error123";
$a = true;
}
}
//var_dump($datos);
if($a == true){
$resultadoJson = json_encode($datos);
//var_dump($resultadoJson);
echo $_GET['jsoncallback'] . '(' . $resultadoJson . ');';
}
?>
The truth is I do not know if I am taking the most appropriate and effective way, please accept suggestions, indications and corrections. Thank you.
My error in the ajax request:
Error en la petición: {"readyState":4,"status":200,"statusText":"load"}
My error in the console:
Uncaught SyntaxError: Unexpected token <
What the data variable prints on the console when my ajax arrives:
jQuery331004199455651714534_1532107113667({"estado":"seleccionado"});
And it marks me an error in my HTML tag, it highlights it with red color and with an 'x' this one.

Warning: Failed prop type: Invalid prop `children` supplied to `TableRow`
Using react-md, I'm trying to build a table from an array of objects. I have one fixed column header but everything else is generated by the keys in the first element of the array.
<TableHeader>
<TableRow>
<TableColumn>Actions</TableColumn>
{Object.keys(list[0])
.filter((key) =>
Object.keys(SEARCH_RESULTS_LABELS).includes(key),
)
.map((key, i) => (
<TableColumn key={i}>
{SEARCH_RESULTS_LABELS[key]}
</TableColumn>
))}
</TableRow>
</TableHeader>
My fixed column is the <TableColumn>Actions</TableColumn> element. The moment I put it in, I get this error. When I remove it, the error goes away.
I'm not sure why this is happening, how do I get rid of the warning?

How does SOCKS configuration works on firefox?
I'm using a manual proxy configuration on Firefox to use a SSH tunnel and everything works fine. However I try to understand how does it works. From my understanding Firefox is just transferring every request to the specified port but I'm not quite sure of what does it means. Also what happen when I don't use a proxy? I guess Firefox is using an other port or something? Basically I'm trying to understand how a web browser connects to internet.

Styling With CSS - Float Removing Styling
I'm new to web development and have discovered an issue that I cant find an answer for. I'm attempting to create a navigation bar following the following guide:
My question is more for learning purposes as it just doesn't make much sense to me and I'm hoping someone can shed some light on it.
Here is the HTML for my example:
HTML
<div id="navigation-bar">
<header id="header">
<nav id="nav-bar">
<a href="#">Tab1</a>
<a href="#">Tab2</a>
<a href="#">Tab3</a>
<a href="#">Tab4</a>
<a href="#">Tab5</a>
<a href="#">Tab6</a>
<a href="#">Tab7</a>
<a href="#">Tab8</a>
</nav>
</header>
</div>
When using CSS to style the guide reference turning each element into blocks using the display:block property and then floating them next to eachother. Much like the following:
<h1>CSS</h1>
nav {
width: 100%;
background-color: #0b98de;
}
nav a {
display: block;
float:left;
border: 1px solid #000;
font-family: sans-serif;
font-size: 9px;
color: white;
padding-top: 20px;
padding-right: 10px;
padding-bottom: 10px;
padding-left: 10px;
text-decoration: none;
}
nav a:hover {
background-color: #17b0cf;
}
But what this appears to be doing is ignoring the properties in the nav block and only applying the properties in the nav a block. For this examples purpose it will leave nav bar white showing only the black border specified in the nav a block. It ignores the background color specified in the nav block and doesnt extend to width:100%. I've tried using the ID identifier as well as a class.
I have found a way to mitigate this by using display:inline-block as below but I still dont understand what the "hidden chain of command" is.
<h1>CSS</h1>
nav {
width: 100%;
background-color: #0b98de;
}
nav a {
display: inline-block;
text-align:center;
font-family: sans-serif;
font-size: 9px;
color: white;
padding-top: 20px;
padding-right: 10px;
padding-bottom: 10px;
padding-left: 10px;
text-decoration: none;
}
nav a:hover {
background-color: #17b0cf;
}
FIDS | Smart Flight Information Display (What tools and methods to create something like this ?)
I believe you have ever seen the Flight Information Displays installed on International or Private airport. The flight information always updates/refresh every time when the data changes or not.
I am SQL Server administrator and T-SQL developer, but i don't know about Web Development (lack of experience like HTML or CSS).
Recently i have a big project of building a custom Flight Information Displays System for myself, fortunately, I got up-to-date information data export from the DB in every minute, the format is anything like this
1,A,TW,XXAirline,663,A3,2018/07/28,00:05:00,2018/07/27,23:36:55,TAE,Daegu,DestinationA,ARRIVED ,B737-800,,,, ,
1,A,IT,ZZAirline,6611,A3,2018/07/28,00:05:00,2018/07/27,23:36:55,TAE,Daegu,DestinationB,ARRIVED, ,,,, ,
2,A,BR,YYAirline, 179, C6,2018/07/28,00:10:00,2018/07/27,23:44:49,KIX,Osaka Kansai,DELAYED ,A321-200,,,, ,
As you can see, those are the raw data which shows exactly the same information as you see on the Flight Information Monitor.
Question : What kind of Web Dev tools could i able to use to build this ? What kind of methods for this dynamic data mining ?
I'm really look forward to hearing some advice from you.

Retaining Firebase auth credentials after redirect
I'm using Firebase authentication (react-firebaseui with Google & Facebook sign-in) in a single page web app in which the user also needs to authenticate against other systems using OAuth redirect flow to gain access to 3rd party APIs.
My problem is that Firebase authentication credentials are lost after the user authenticates to these 3rd party systems through OAuth (redirect flow).
How can I retain the Firebase authentication session and regain Firebase credentials after the redirect?
I've tried persisting the authentication credentials and then invoking signInAndRetrieveDataWithCredential after the redirect, but this doesn't appear to work.
How to get Filename and Filepath in Django based on a Model containing Fileupload?
I making a email delivery WebApp, I have an Email Class with uploadcsvfile to upload the .csv contact file from the user's computer to server at location CONTACT_DIR, what I'm unable to figure out is how to get the saved contacts_some_char.csv name in my views.py, the purpouse of getting it's name is so that I can parse the email list and send email to them.
I have my model.py as follows :
class Email(models.Model):
fromemail = models.EmailField(blank = False, max_length = 254)
uploadcsvfile = models.FileField(upload_to = 'Contacts', blank = False)
subject = models.CharField(blank=False,max_length = 254)
bodyHeading = models.CharField(blank = False,max_length = 254)
bodytext = models.TextField(blank = False)
name = models.CharField(blank = False,max_length = 254)
Here is my views.py :
def index(request):
if request.method == 'POST':
email_form = EmailForm(request.POST, request.FILES)
if email_form.is_valid():
email_form.save(commit = True)
print(Email.uploadcsvfile)
contacts = Contacts()
#path = settings.CONTACT_DIR
f = open(settings.CONTACT_DIR+"/"+str(uploaded_file_name))
csv_f = csv.reader(f)
Emails = []
Names= []
L_Names = []
for x in csv_f:
Emails.append(x[0])
Names.append(x[1])
L_Names.append(x[2])
f.close()
contacts.ListOfEmails = json.dumps(Emails)
contacts.ListOfFirstNames = json.dumps(Names)
contacts.ListOfLastNames = json.dumps(L_Names)
contacts.save()
Here is forms.py for the same :
from django import forms
from dcsvreader.models import Email
class EmailForm(forms.ModelForm):
class Meta():
model = Email
fields = "__all__"
A.K.A How do i get uploaded_file_name in views.py, I'm reading in various QnA at S.O that this is related to FileDescriptor but can't find how exactly also, print(Email.uploadcsvfile) gives <django.db.models.fields.files.FileDescriptor object at 0x03F7DF90> as output.
Tips on creating a web & mobile application
I'm currently trying to learn new frameworks and languages, since it's summer and I have loads of free time. I've decided I should create an application that is deployed in both the web and mobile. As a developer who has knowledge in vanilla:
- PHP.
- JavaScript & jQuery.
- Android.
What frameworks should I use to build my app? Should I use a backend API for both apps, or should I seperate them?
Frameworks I'm considering are:
- For the web: MEAN Stack or Angular/React + PHP/J2EE.
- For mobile: React Native/Native Android + PHP/J2EE.
- For database: MongoDB or MySQL/PostgreSQL.
I'd like to know which frameworks should I learn first, and should I actually go with vanilla PHP for backend or a framework such as Laravel or Symfony.
P.S: I'm only trying to learn new stuff, I'm not looking to create a sophisticated app, but rather an app with an idea that requires learning several frameworks at once.
Getting empty string as a response from a web server app
I have a web server app, and a client app that works like a browser. I get the desired response from the server app if I type my IP in the browser window, if I read the response to the client app I get an empty string. The client app works only if I read the URL of a website, but not with my IP.
Client:
#include "stdafx.h"
#include "WinHttpClient.h"
#include <iostream>
#include <fstream>
#include <algorithm>
#include <regex>
#include <string>
#include <vector>
#include <sstream>
#include <utility>
using namespace std;
int getResponse(wstring url) {
WinHttpClient client(url);
client.SendHttpRequest();
wstring page = client.GetResponseContent();
wcout << page << endl;
return 1;
}
int _tmain(int /*argc*/, _TCHAR** /*argv*/)
{
//wstring url = L"http://yahoo.com";
wstring url = L"104.171.115.164";
getResponse(url);
char a;
cin >> a;
return 0;
}
Server:
#pragma comment(lib, "WS2_32.lib")
#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <direct.h>
#include <winsock2.h>
long nbytes;

listen(listenfd, 64);
for (hit = 1; ; hit++)
{

Multiple update query in Razor Pages .ASP.NET
I'm trying to develop a tiny front-end for a sqlite DB using Razor Pages (NOT MVC!).
Looks like it supports SQL in a different way, not like I used to in the past.
For example, I need to re-assign value to the field Pl_Pos (position of the record in the list). Now I do this like that:
for (int i = PlnPos + 1; i<= PlModelIndexModel.PlnModelTotal; i++)
{
PlnModel PlnModelRedo = await _context.Plane_Models.FirstOrDefaultAsync(m => m.Pl_Model_Pos == i);
PlnModelRedo.Pl_Model_Pos = i - 1;
_context.Attach(PlnModelRedo).State = EntityState.Modified;
await _context.SaveChangesAsync();
}
Is there any other way to do it more efficient and do something like:
Update Pl_Models set Pl._Models.Pl_Pos = Pl_Models set Pl._Models.Pl_Pos - 1 where Pl_Models set Pl._Models.Pl_Pos > PlnPos
I stuck a bit...
Thanks in advance!
How to convert static site to dynamic site
I recently built a React site using the static site generator Gatsby.JS and was wondering if there was an easy way for me to convert it to a dynamic site? I'm not sure what's best, extract the Gatsby, deploy as dynamic?
Dollar symbol in eval function php
I am trying to use the eval() function in PHP, but one of my variables (ppi) has a dollar symbol in it.
$operation = "*";
$cname = mysqli_real_escape_string($link, $_REQUEST['cname']);
$to = mysqli_real_escape_string($link, $_REQUEST['email']);
$prod = mysqli_real_escape_string($link, $_REQUEST['prod']);
$desc = mysqli_real_escape_string($link, $_REQUEST['desc']);
$ppi = mysqli_real_escape_string($link, $_REQUEST['ppi']);
$items = mysqli_real_escape_string($link, $_REQUEST['items']);
$total = mysqli_real_escape_string(eval('return '.$ppi.$operation.$items.';'))
Although simplified, the equivalent could be:
$operation = "*";
$cname = mysqli_real_escape_string($link, $_REQUEST['cname']);
$to = mysqli_real_escape_string($link, $_REQUEST['email']);
$prod = mysqli_real_escape_string($link, $_REQUEST['prod']);
$desc = mysqli_real_escape_string($link, $_REQUEST['desc']);
$ppi = '$10';
$items = '5';
$total = mysqli_real_escape_string(eval('return '.$ppi.$operation.$items.';'))
Whenever I try to run this code though, I always get a HTTP error 500.
Thank you in advanced,

Completely lost and not sure what to study regarding web & mobile dev
I've been studying programming for a year, and not sure what I should study from now on.
I learned...
- College introductory level python course
- College introductory level java course
- Mathmatical logic
- HTML / CSS
After studying about a year, I came up with two goals, but I'm completely lost, and not sure what I should study to achieve them.
I want to develop a webpage that...
- runs on AWS
- includes web community (thread / non-thread)
- can take polls and ratings of different entities from users
- suggest best matching entities for individual users based on their past polling and ratings database
I also want to develop an application...
- scheduler app for android/ios that can sync with Google/Apple callender
- which can also sync with Google map and
- sync & take inputs from massenger apps (such as Facebook Messenger, etc)
I browsed through the web for weeks, and at one point, realized that more I search, more I get confused. So I thought that it would be much better to ask for an advise, and follow the given advice until I learn enough so I can make judgement for myself with given information on the web.
Can anyone please suggest a way for this lost wretched soul? What should I study from now on? What would be a good starting point? What tools should I familiarize with? Any advice will be great help.
Thank you very much.
Instead of scrolling, shrink top section of page until it reaches a certain size, then allow scrolling
So, the top of my page is a full-page (100vw x 100vh) div with a (let's say 100)px fixed navbar at the top. When the user is at the top of the page and tries to scroll, I'd like them to remain at the top of the page, but for the top div to shrink in response to their scrolling, until such point as the div becomes the height of the navbar and essentially becomes the background for it; then, scrolling can continue as normal.
When the user scrolls back up, I'd like the process to reverse and the div to return to full size. I really hope there's a pure CSS solution for compatibility and responsiveness's sake, but JavaScript works great too.
I've been working on a JavaScript solution with the littlest bit of heavily flawed success - I've been using $(window).scroll(), getting the distance scrolled, shrinking the div by that, and then e.preventDefault() or window.scrollTo(0,0). This is a really dirty solution that doesn't work well at all in most cases, and I'm at a loss for a better one...
Thanks so much for any help!

Workplace peers interaction
In the IT industry, how do you cope/deal/manage with double thinking ( or n thinking ) in the workplace ? From what my current experience is telling me, people sometimes are talking about a technical software aspect, but they are thinking about one or many other non-technical specific things. While this is not a problem by itself, acting on particular ideas could be disastrous or illegal.
Angular - Event OnScroll
I'm developing an application in angular 4. Also I'm using Firefox and everything works fine, I can handle the scroll event like this:
@HostListener('window:scroll', ['$event']) onScrollEvent($event) {
let posY = $event.pageY;
}
The posY starts from 0 which is fine.
But now I'm testing the same application in Google Chrome or Safari and I get "pageY undefined"
I was looking at google that Chrome and Safari not handle PageY. Is there any way to get this value using angular ?
Thanks
UPDATE:
I also tried
console.log($event.target.body.scrollTop);
but keep me showing 0

Web client Interface for machine learning model
Is there a framework, template that I could use as a reference for my below use case.
I want to create a client web interface that allows non-technical users to upload files & perform some analysis over data. It should give them access to data they have uploaded in the past.
The uploaded files would be sent to my back end which has a machine learning model which would output the result, which should be sent to the web interface.
Please let me know if my question is ambiguous, so i could amend it. Thank you for reading.
Is there a UI development IDE for web as there is for Android
Does anyone know if there's an IDE that would let me design web pages the same way an app view can be designed on android? what I mean specifically is the way you can position elements in relation to each other by connecting them with arrows and springs in android studio
please help me to find the error in my code...!
